Brake grinding

Hey everyone. So I have a 2015 off-road just hit 75,000. Brakes started lightly grinding Sunday then grinding awfully Monday morning. There was no warning squeak at all I would have noticed.

just took the tires off and yea the pads look pretty flat all around. Does not look like a sticking caliper.

got new pads but I have a twofer question.

has anyone had a real hard time getting these pins out? The videos I’ve watched made it look much easier.



do I need new rotors?



sorry for the awful pics. It’s dark and rainy and I just want to get this done.

 

Noise could be bad wheel bearings

 

What would that require just remove the rotor and put a new pack in there?

 

Sorry to hear about your troubles.....I would try using a center punch and tap them out. It looks like you've sprayed them already. When you reinstall them make sure you put some brake lube on the pins. If you're putting in new pads I would replace the pins as well
Those rotors look like they are in bad shape....do you have access to a lathe or someone that can turn them down if they are not to thin? You might want to price out new rotors as well....
You have a lot of salt in your state of NJ....no wonder the rotors are in bad shape....Good luck and stay safe.

 

This ^^^^

and yes you need new rotors.

 

While you replace your rotors check out @crashnburn80 brake upgrade! I did it to my truck and it's a good improvement over stock!

 

New pads, new rotors. If the old ones can be turned, you might want to consider doing that and saving them for the next brake job.
Not too many auto parts stores turn drums and rotors anymore. You may have to call around.

 

looks like bad wheel bearings. Pry the rotor up and down and check for play. Probably why it wore the edge out

Though it sounds like the OP already has replacement pads.

 

is this just a different rotor or actually upsizing the whole braking system.

 

Different rotor designed with increased cooling and more mass for greater thermal capacity, it is stock size. The rotor helps the brakes run cooler and helps prevent overheating. Then using Toyota’s more aggressive TRD pads, which helps with more bite from the brakes.

 

Unfortunately, the pictures you provided of your rotors only show the outside face. The outside face on them doesn't look bad -- just a small bit of rust that will easily be cleaned up when turned, or if you cheap out, by your disk grinder.

Grinding *usually* means that the pad material is *completely* worn away on at least one pad. I'd imagine therefore, that one of the back sides has probably experienced this. If you have grinding but it hasn't gone on too long, it *may* be possible to turn it and use again, or it is also possible that the surface has been gouged too deeply.

However, given that you can get good quality aftermarket coated rotors for ~$35 each (https://www.rockauto.com/en/moreinfo.php?pk=8923736&cc=3310143&jsn=29&jsn=29), there really isn't a lot of reason to muck around with them.

For getting the pins out;
1) Oil them really well.
2) Pull the clips from them.
3) Whack the head of the pins a few times really good to hopefully loosen them up.
4) Grab a hardened ~1/4" bolt in vice grips and hold in-line with the pin opposite the head and whack it with a heavy hammer until it drives the pin out.

*** I do not suggest drilled or slotted rotors unless you really need to match the hello kitty theme of the rest of your vehicle. They wear faster and are more fragile than straight flat rotors.

 

I had a frozen caliper on my ‘15.

Those pins were rusted on so bad I had to cut two off after using a hammer and punch.

Definitely go with @crashnburn80 ’s upgrade- I did. It’s a great idea with only a bit additional cost.

BTW, removing and relubing the pins are now part of my routine tire rotation maintenance.

 

It could have been worse. I'd think you'll be find just getting those turned. My 07 still has the original rotors at 202,000 miles. they've been turned twice i think. I'll need new rotors next time.
